Strange Noise, Please Help!!

[bjblackout]

I have a 2008 Limited with 34,000 miles on it and when driving at exactly 35mph and then hitting the gas with a little force to accelerate every single time I get like a vibration type sound from the front somewhere. I can make the truck do this like clockwork every single time and was just wondering if anyone has any idea what it may be??

So to sum up if you drive steady at 35mph and hit the acclerator I get a noise like vibration or rubbing for a split second and then acceleration happens. Any ideas??

Once I had a loose stick-on wheel weight that at certain speeds would tap the brake caliper. Doesn't sound like your problem, but something to rule out.
Bearings? Axles? Seized caliper?
So you get this noise, "then acceleration happens" Does it feel like whatever is happening is hampering acceleration?

Truck is at dealership for TSB for friction plates. I have had this truck for two months and it has been back to the dealer twice for tranny problems. Not feeling real good about my purchase right now!!
